Which of the following statements is true about the momentum of a person jumping from a tree to the ground? a) The momentum of the person would stay the same. When the person hits the ground, their momentum would be the same value as the momentum they had when they jumped from the tree. b) The momentum of the person would be reduced to zero when they hit the ground. c) The momentum of the person would increase. When they hit the ground the momentum of the person would be greater than the value of their momentum when they jumped from the tree. d) The momentum of the person would decrease but not be zero. When they hit the ground the momentum of the person would be less than the value of their momentum when they jumped from the tree but not zero
